【發明所屬之技術領域】 尤指利用於 本發明主要係揭示一種起子的工具夾頭 動力工具驅動之起子工具夾頭。 【先前技術】 六角柱狀的起子頭已經是—種標準，不但可 求來替換起子頭的前端形式，起子職端的 : 接在不同雜的爽頭上，各家H商都會針對起子付 相對端角的尺寸為標準來做出相應的夾頭工具，利用 工具就可以驅動夾頭帶動起子頭進行施工。 請參照美國專利號第6,345,56G號之「Clampingchuck for bits」專利案，其為一種用於銜接起子頭的夾頭， 一端设有一個工具夾持件（t0〇ih〇lder)，另—端具有 其 個六角狀的結合部（clamping porti〇n)。在工具夹持件 外設有一個調整套（actuating sieeve)用來控制一個設 於工具夾持件上的鋼珠（ball)，使鋼珠能夠固定起子頭 (bit)。所述的調整套前端通常會在外周圍形成錐狀的結 構，也就疋s周整套罪近如端處的外徑會小於調整套遠離前 端處的外徑，這是為了要讓整個夾頭能夠較容易的進入孔 内進行施工。 雖然6, 345, 560 —案的夾頭在調整套外周圍做了由細 •5C粗的錐度設計來使炎頭能夠更加的進入孔内進行施工， 但在實際使用上仍然是會遇到夾頭無法進入孔内進行施工 5 1332891 的問題。這是因為戲㈣最大外_然大於孔徑，所卩 、 夾頭實際能夠進入孔内的距離相當有限，如此，導致許多 、 的場σ疋恶法採用動力工具來驅動此種夾頭來進行施工的 作業，因為夾頭無法讓起子頭帶動螺件進行施工。 這種情況下，使用者必須要替換一個加長形的起子 頭，使螺件能夠確實的接觸孔内的施工處，但是這樣又衍 生了另-個問題’就是動力工具的驅動端與螺件的距離變 長了，如此，動力工具的驅動端旋轉時，過長的起子頭與 螺件之間會晃動的很嚴重，即便使用者以手握持在調整套籲 的=周圍時，仍然無法有效的降低起子頭晃動的問題，這 樣會使施工品質相對的降低，甚至導致施工處的損壞。 一除此之外’6,345,56〇 -案的夹頭在工具夾持件内設 . ^-個磁鐵（magnet)絲吸住起句，能夠在調整雜 . 雨端推，，鋼珠呈釋放狀_，防止起子頭脫離工具減 L但疋肷設於工具祕件内的麵磁性會被王具夾料 · 分散，使得錢_性變弱，因此無树實的吸住起子頭， 仍然會發生起子職離工具祕件的_，如此，在施工 作業上就會有Μ簡產生，亦影響了施工的速度。 請參照美國專利號第6,637,755號之厂⑶㈣― iniature tool bits」專利案，其為另一種用於銜接 (子員的爽頭’其一端設有一個套筒（socket)，另-端 ^有個/、角狀的桿（spindle)。在套筒外設有一個襯套 也㈣）用來控制一個設於套筒上的鋼珠（ball)，使 綱朱月b夠固疋起子頭（bit)。所述的概套前端通常會在外 6 周圍形成錐狀的結構，也就是襯套靠近前端處鈞外徑會小 於襯套遠離前端處的外徑，這是為了要讓整個夾頭能夠較 容易的進入孔内進行施工。 雖然6, 637’ 755 —案的夹頭在襯套外周圍做了由細變 粗的錐度設計來使夾頭能夠更加的進入孔内進行施工’但 在貫際使用上仍然是會遇到夾頭無法進入孔内進行施工的 問題。這個夾頭無法進入孔内施工的問題與前述 6,345,560 —案的問題一樣沒有被解決，故6,637,755 一 案亦存在有相同之缺失。 除此之外，6, 637, 755 —案在套筒内設有推動件 (Pusher)來把起子頭推出套筒的容室（chamber)外，提 供了一個方便取用起子頭的效果，但是這樣的設計存在一 個很大的問題，就是當襯套往後端移動使鋼珠呈釋放狀態 時，起子頭立即失去了固定的力量’故起子頭會直接被推 動件彈性的推出套筒外而掉落，形成替換起子頭的一大困 擾。 · 有鑑於上述習知結構之缺失，本發明人乃發明出一種 起子的工具夾頭，其係可克服上述習知結構之所有缺點。 【發明内容】 本發明起子的工具夾頭所欲解決之技術問題係在於， 傳統的爽頭在固定起子頭之後若要進行深孔的施工作業， 就會遇到夾頭外徑過粗而無法進入孔内 工作的問題。 本發明提供一種起子的工具夾頭，其主要目的是在相 1332891 =於連制的有效長度範_，在套f段的套合孔内是力 /有延伸出任何凸塊也沒有任何凹槽的結構，使得夾頭的= 搜可以縮到最小，以利於夾頭直接伸人孔内進行施工。 .本伽起子的工減翻次要目的在於，提供— ^對於連接_有效長度範_，轉段的最大厚度金連 ，段的最小厚度都能夠有效減少的夾頭結構夹 直接伸入孔内進行施工。 〜π又頭 :發明起子的工具夾頭的另—目的在於提供 =辑接段後端’使拉套能夠朝向後端被拉動，而 且拉套目騎本體轉的夾頭結構。 本么明起子的工具夾頭的另一目的在於，提供 =:磁鐵吸引之後還能夠具有足夠磁性來吸附螺件4 本叙明起子的工具夾頭的又一目的在於 1=藉由拉套的酬定起子頭或夹緊起二夾 描述= 二==明的新顆特性將從以下詳細的 【實施方式】 兹舉— ，在專利 有關本發明所採用之技術、手段及其功效， t實施例並配合圖式詳述如後，此僅供說明之用 申凊上亚不受此種結構之限制。 參照圖一至圖三 為本發明之夹頭的第一個實施例， 8 1332891 其包括有一本體10、一拉套20與一夾緊元件3·〇 ;其中： 該本體10包括有一個驅動段11與—個結合於驅動段 一端的連接段12。在本貫施例中δ玄本體1 〇的驅動段u 與該連接段12是一體之結構’而且驅動段11具有六角棍 狀之橫截面，連接段12具有圓筒狀之橫截面。驅動段u 具有一個前端與一個後端’驅動段11的前端係結合於連接 段12的一端’驅動段11的後端係供銜接動力工具9〇的驅 動端91 (如圖五），使驅動段11得以透過動力工具9〇的 驅動端91帶動而跟著旋轉。驅動段11具有六角柱狀之外 表面。連接段12具有一個前端與一個後端，連接段12的 後令而結驅動段11的前端形成一體之結構。 請同時配合參照圖四，連接段12於前端軸向設有—個 橫截面呈六角形之連接槽14，連接槽14用以連接起子頭 93。連接槽14具有六個彼此呈—百二十度夾角的連接平面 141，兩個連接平面丨41之間形成一個角落U2。起子頭卯 能夠插入連接槽14的最深處，並且使六個連接平面、ΐ4ΐ =的接觸在起子頭93的外表面’當連接段跟著驅動 ^旋轉時，戶斤述的六個連接平面141能夠提供帶動起子 =3轉動的效果。連接槽14具有—個有效長度l (如圖 面接奶軸平面141與起句93外表 向距離，是連接槽14用來帶動起子頭93旋轉 :払觸長度，也就是說 > 連接槽14開口的導角因為产 跟起子頭93外表面接觸，所以不屬於有效長度L的二部 刀連接段12的外表面具有一個呈圓柱狀的筒壁，筒 9 壁15具有均一的直徑。連接段12的筒壁15靠近連接槽 14開口處環設有一個容置槽16，容置槽16内形成有至^ 一個限位槽161 ’依圖中所示為一個限位槽161，限位槽 161具有一個連通於連接槽14中一個角落142的限位孔 162。 連接段12靠近後端的外表面設有一個直徑小於連接 段12筒壁15直徑的套接段17，而且因為套接段17的直 徑小於筒壁15的直徑，所以連接段12在套接段17與筒壁 15之間形成一個肩部171。連接段12於套接段17靠近驅 動段11的位置還環設有一個止擋槽172。 連接段12内設有一個橫截面呈圓形的容置空間18 , 谷置空間18與連接槽14連通。連接段12的筒壁15相對 衣谷置空間18的位置開設有一個徑向的穿孔181。 拉套20係套設於本體1〇外，而且能夠相對於本體 產生軸向位移關係及圓周方向的旋轉關係。拉套2()包括有 段21與—個結合於套管段21 —端的拉環段22， & '係套5又於連接段12外，而且能夠相對於連接段 2產=向鄉_、及關方_轉_。套管段Μ 個橫截面呈圓形 具有均一的吉菸，太人 备。孔Z11 15 n乾 套合孔211是套設於連接段12的筒壁 係。套管連接段12之·夠產生相對之旋轉關 壁212具奸^面具有—個呈陳狀的管壁⑽，管 的直徑，而曰1 套合孔211的直徑小於管壁犯 套合孔211的直徑等於筒壁15的直徑。至於 10 套合孔21]與筒壁15之間的公差與配合，已非未案所論述 之重點，故不再加以贅述。 在相對於連接槽14的有效長度L範圍内，套管段21 七著半徑方向從套管段21最大徑的管壁2丨2至套管段 最】、從的套合孔211的徑向距離形成一個最大厚度Τ2ΐ， 在套s段21的套合孔211内是沒有延伸出任何凸塊也沒有 任何凹槽的結構，而且在所述的最大厚度内是沒有任 何凹槽的結構’也就是說，在所述的最大厚度T21内是没 有再額外加裝其他元件的空間，因此，在㈣於連接槽^ 的有效長度L範圍内，連接段12筒壁15直徑的—半: j去連接槽14兩相對角落142的直經的一半距離形成 取小厚度T12’絲段21的最A#《T21是小 的最小厚度T12。 由於套管段21在姆於連接槽14的有效長 内的取大厚度T21是沒有任何凹槽或凸塊的 ^ 確保套管段,21的最大厚度T21能夠做的相當=就 連接段12的筒壁15直徑縮小，使得本發明 且礒 套管段21直接伸人小孔㈣工作環境，_讓== =伸入小孔徑的深處進行施工’有效減少被阻礙的情= 而且，由於套管段21的最大厚度τ 薄，而且能夠比連接段12的最小厚声T12 ^做的相當的 明的夾頭在相對於連接槽14的有^=本發 21的管壁212直徑是能夠做的相當的細，使得本^ = 1332891 輕巧的優點’而且更達到了節省材料的效 果，使用上亦更財便於攜帶的功能。 拉環段22之1係'結合於套管段21之 環段㈣套設於連接段12之㈣處。減 = 一個橫截面呈圓形之容孔23,拉 竿门又有 設有-個凸環24,拉環段22心1 ;

[Prior Art] The hexagonal column-shaped screwdriver head is already a standard, not only can be used to replace the front end form of the screwdriver head, but also the front end of the screwdriver: on the different kinds of cool heads, each H-business will pay the opposite end angle for the screwdriver. The size is standard to make the corresponding chuck tool, and the tool can drive the chuck to drive the screwdriver head for construction. Please refer to the "Clampingchuck for bits" patent of U.S. Patent No. 6,345,56G, which is a collet for connecting a screwdriver bit, one end of which is provided with a tool holder (t0〇ih〇lder), and the other end It has a hexagonal joint (clamping porti〇n). An actuating sieeve is provided outside the tool holder for controlling a ball placed on the tool holder to enable the ball to secure the bit. The front end of the adjusting sleeve usually forms a tapered structure on the outer circumference, and the outer diameter of the entire set of sin is as small as the outer diameter of the adjusting sleeve away from the front end, so that the entire collet can be It is easier to enter the hole for construction. Although the collet of the 6, 345, 560 case has been made around the outside of the adjustment sleeve by a thin 5C taper design to allow the head to enter the hole for further construction, it is still encountered in practical use. The head cannot enter the hole for the problem of construction 5 1332891. This is because the maximum outer surface of the play (4) is larger than the aperture, and the distance that the collet and the collet can actually enter the hole is quite limited. As a result, many of the field σ abomination methods use a power tool to drive the collet for construction. The operation, because the chuck can not let the screwdriver head drive the screw for construction. In this case, the user must replace an elongated starter head so that the screw can reliably contact the construction site in the hole, but this creates another problem, which is the drive end and the screw of the power tool. The distance becomes longer, so that when the driving end of the power tool rotates, the excessively long screwdriver head and the screw will sway very seriously, even if the user holds the hand around the adjustment sleeve, it is still not effective. The problem of reducing the shaking of the screwdriver head will result in a relative decrease in the construction quality and even damage to the construction site. In addition to the '6,345,56〇- case, the chuck is set inside the tool holder. ^- Magnet (magnet) wire sucks the sentence, can adjust the miscellaneous. Rain push, the steel ball is released _, to prevent the screwdriver head from falling out of the tool minus L, but the magnetic properties of the surface set in the tool secrets will be dispersed by the kingware, making the money _ sexually weak, so the tree head will not suck, it will still happen The driver's job is away from the tool's secret _, so there will be simplifications in the construction work, which also affects the speed of construction. Please refer to the US patent number No. 6,637,755 (3) (4) "iniature tool bits" patent case, which is another kind used for articulation (the cool head of the child's one has a socket at one end, and the other end has a /, angled rod (spindle). There is a bushing outside the sleeve (4)) to control a ball on the sleeve, so that Zhu Zhuyue b is enough to fix the bit (bit) . The front end of the jacket usually forms a tapered structure around the outer portion 6, that is, the outer diameter of the bush near the front end is smaller than the outer diameter of the bushing away from the front end, in order to make the entire collet easier. Enter the hole for construction. Although the collet of the 6, 637' 755 case has been made by a thinner and thicker taper around the bushing to allow the collet to enter the hole for further construction, it is still encountered in the continuous use. The problem that the head cannot enter the hole for construction. The problem that the chuck could not enter the hole was not solved as in the case of the above-mentioned 6,345,560-, so the same lack of the 6,637,755 case. In addition, 6, 637, 755 - the case has a pusher in the sleeve to push the screwdriver out of the chamber of the sleeve, providing an easy access to the screwdriver head, but A big problem with this design is that when the bushing moves to the rear end and the steel ball is released, the screwdriver head immediately loses the fixed force. Therefore, the screwdriver head is directly pushed out by the elastic push-out sleeve of the pusher. Falling, forming a big trouble to replace the screwdriver head. In view of the above-described deficiencies in the conventional structure, the inventors have invented a tool holder for a screwdriver that overcomes all of the disadvantages of the above-described conventional structure. SUMMARY OF THE INVENTION The technical problem to be solved by the tool holder of the present invention is that if the conventional cool head is to perform deep hole construction work after fixing the screwdriver head, the outer diameter of the chuck is too thick to be The problem of working inside the hole. The invention provides a tool holder for a screwdriver, the main purpose of which is that the phase 1332891 = the effective length of the joint, the force in the sleeve of the sleeve f is / the extension of any bump and no groove The structure allows the chuck to be minimized to facilitate the construction of the collet directly into the hole. The purpose of the work of the gamma screwdriver is to provide - ^ for the connection _ effective length _, the maximum thickness of the segment, the minimum thickness of the segment can effectively reduce the collet structure clip directly into the hole Construction is carried out. ~π又头: Another purpose of the tool chuck for inventing the screwdriver is to provide a rear end of the joint section to enable the pull sleeve to be pulled toward the rear end, and to pull the sleeve to ride the body to rotate the chuck structure.

The pull ring segment is provided with a circular hole 23 having a circular cross section, the pull ring segment 22A is provided with a convex ring 24 in the ring, and the convex ring 24 of the pull ring segment 22A (2) is connected to the tubular wall of the segment 12 The diameter of 15 and the outer surface of the drive section U are smaller than the diameter of the collar 24 of the tab section 22A. For example, the collar 24 can be contacted at the rear end of the connecting section. A reset element 40 is disposed between the segment 22A and the body 1〇, and the common pull ring segment 22A generates a force axially moving relative to the body 1〇 in the complex direction. The reset element 40 has a first end 41^12 end 42, and the convex ring 24 of the pull ring segment 22A is straighter than the straight bore 23 of the bore 23; the first end 41 of the reset element 4Q can abut the pull ring segment 22a The vestibule 24, the second end 42 of the resetting member 40 has a smaller diameter than the first end 41 is disposed in the stop slot 1U of the driving section U, so that the restoring element 4 匕 in the 匕 23 enables the tab section 2 to Relative to the present engraving, the g is moved axially in the direction of the connecting section 12. The reset 1 in this embodiment is a spiral compression magazine that is sleeved around the outer periphery of the driving section 11. Or the detent element 30 is disposed in the receiving groove 16α of the connecting section 12, and (4) the reduction is pure enough to be partially exposed to the connection, and the 142' is as shown in FIG. In the present embodiment, the detent element 30 ς a card abutment 31 Α is separated from the two nip portions 31 被The card abutting portion 31 is received in the U-shaped shape and placed in the limiting groove 16u. The two clamping segments 32 are arranged in an arc shape to be accommodated in the receiving groove m, and the two clamping portions 32 are opposite to the locking portion 31Α. One end of the wire forms a string, the length of the string is smaller than the diameter of the receiving groove 16A, and the string forms a superior arc-like structure to the clamping member 30A. Thus, the clamping section 32A can move the abutting portion 31A toward the limiting hole 162 to partially expose the engaging portion 31A to the corner 142 of the connecting groove 14, and prevent the clamping member 3A from being disengaged from the receiving groove. The shape of the clamp member 30A of this embodiment is a structure in which a metal wire is bent. The ejector seat 50 is disposed in the body 1 , for contacting one end of the driver head 93. The pusher base 50 includes a block 51 and a magnet 52 embedded at the end of the block 51. The insert 51 is disposed in the receiving portion 18 of the connecting portion 丨2, and the magnet 52 is exposed with a magnetic pole at the connecting groove 1 & for magnetizing the screwdriver head 93 to make the magnetic head 93 magnetically Adhesive screw is committed. 20 1332891 In order to make the magnetic properties of the magnet 52 fully absorb the screw 92 via the screwdriver head 93·, the magnetic material is prevented from being dispersed. The material of the insert 51 in this embodiment is copper, and the material of the connecting portion 12 is stainless steel, such as Austenitic stainless steel. The elastic device 60 is the same as the first embodiment described above, and thus will not be described again. Further, the state of use of the chuck of the present invention is similar to that of Fig. 5. When the bit 93 is fixed to the joint groove η, the construction work can be performed. The chuck of the present invention is connected to the driving end 91 of the power tool 9 by the driving section 11, and the driving end 91 is rotated to drive the chuck to rotate synchronously with the screwdriver head 93. In a general case, the user holds the power tool 9 以 with the left hand, and the screw 92 is placed at the front end of the screwdriver head 93 by the right hand, and the screwdriver head 93 has the effect of absorbing the screw 92 due to the magnetic force of the urging seat 5 〇. Therefore, the screw member 92 is magnetically attracted by the screwdriver head (10) without falling. At this point the user's right hand can leave the screw 92 and grab another screw 92 to prepare for the next construction. While the user's right hand leaves the screw 92, the user's left hand moves the power tool 90 forward', allowing the screw 92 in front of the chuck to break into the work. After the completion of the construction, the other screw member 92 obtained by the left hand can be immediately placed at the front end of the screwdriver head 93, and magnetically adsorbed by the screwdriver head 93, and then the above action is repeated to achieve the effect of rapid construction. That is to say, the effect of the magnetic heading member 92 generated by the screwdriver head 93 is provided by the ejector base 50, and the action of the user to hold the screw member into the workpiece with the left hand can be omitted, and the construction time is saved. Speed construction - fruit. In the construction, if the copper work material is harder than the day: the force ° or the angle of the screw 92 attacking the artificial crop has an inclined angle, use: also = enough to hold the outer surface of the pull sleeve 20 with the left hand, for example, the sleeve The pipe wall 212 of the pipe section 21A, such that when the collet is rotated by the driving end 91 of the power tool 9 ', the gripping of the non-synchronously rotating casing section 21A can provide the screw member with a relatively stable effect of attacking the artificial crop. It also improved the construction yield. The pull sleeve 20 of the present invention can be moved between the @ fixed position and the release position. When the pull sleeve 20 is in the fixed position, as shown in FIG. 10, the sleeve portion 2 of the pull sleeve 2 is covered by the sleeve hole 211 to the connecting portion 12 The accommodating groove (10) is outside, and the sleeve hole 211 is blocked by the clamping portion 3U_ of the clamping member 3A, so that the inside of the clamping portion 31A of the clamping member 3QA can be partially barely connected via the limiting hole. The H 142 of the groove 14 and the inner side of the card abutting portion 31A are inserted into the positioning groove 931 of the bit 93, so that the clamping member 3A reaches the effect of fixing the bit 93, effectively preventing the bit (10) from being improperly applied. The screw is like the father's death, causing the problem that the screwdriver head 93 is pulled away from the connection slot 4. Mai Zhaotu 12' is the pull sleeve of the chuck of the present invention. (H is a state diagram of the release position. The user can move the pull sleeve 2Q via the pull ring segment 22A to move the pull sleeve 20 to the release position. When the sleeve 2 is in the release position, the sleeve section 21A of the sleeve 2 is completely away from the outer circumference of the accommodation groove (10), so that the outer side of the inch-receiving section 31A of the refreshing member 30A is not covered by the sleeve 2〇. The inner side of the card abutting portion 31A of the component is still clamped by the limiting hole 162A to prevent the screwdriver head 93 from falling off. The pusher seat 50 is now pushed by the elastic device 60 to enable the driver bit 93 to be connected to the slot. The inner side of the outer wall 14 is pushed outward to increase the distance of the bare metal outside the connecting groove 14 to provide an effect of using the screwdriver head 93 more easily. The dissimilar head (10) is clamped by the tightening element 30A. Therefore, when the screwdriver head 93 is pushed out by the push-up seat 5〇, the 22 1332891 is not ejected from the connection slot 14 to effectively avoid the problem of the screwdriver head. ▲ The two-in-one chuck cover 20 is returned to the fixed position.

The elements of the foregoing embodiments are denoted by the same reference numerals, and only new symbols are added for the new elements. In the present embodiment, the tubular wall I5 of the connecting section 12 is adjacent to the opening of the connecting slot, and a receiving groove 16D is formed in the ring. The receiving groove (10) is formed with at least one limiting groove 161D, as shown in the figure. a limiting slot 10 (10), the limiting slot W1D has a limit ^ W2D connected to a corner 142 of the connecting slot 14. The positioning member 31D is disposed in the limiting groove 161D, and the positioning member 31D is partially exposed to the corner of the connecting groove 14 via the limiting hole 162D. The clamping member 30D has an arc-shaped clamping portion 32]). The missing portion 32D is accommodated in the accommodating groove and is in contact with the outside of the positioning member 31D, and the two ends of the clamping portion 32D are connected to form a string, and the chord length is smaller than the diameter of the accommodating groove 16D, and The chords described will clamp the components into a superior arcuate configuration. Thus, the clamping section 32D can move the positioning member 31D toward the limiting hole 162D to partially expose the inner side of the positioning member 310 to the corner 142 of the connecting groove 14, and prevent the clamping member 30D from coming off the receiving groove 16D. The shape of the clamping member 30D of the present embodiment is a structure in which a metal wire is bent, and the positioning member 31D is a bow-shaped structure. m Tea Figure 17 is a sixth embodiment of the collet of the present invention, and the embodiment 25 1332891 is substantially the same as the first embodiment (or the second embodiment). The difference is that a positioning member 31E is provided between the clamping member chamber and the driver bit 93, and the effect of clamping the driver head 93 or fixing the driver head 93 can also be achieved. In order to facilitate the description and understanding of the features of the present embodiment, elements in the present embodiment that are the same as those in the foregoing embodiments are denoted by the same reference numerals, and only new symbols are added for the new elements. In this embodiment, the wall 15 of the connecting section 12 is adjacent to the opening of the connecting groove 14 and is provided with a receiving groove 16E. The receiving groove (10) is formed with at least a limit position 3 161E 'as shown in the figure. The limiting slot (8)e has a limiting hole 162E that communicates with the corner 142 of the connecting slot 14. The valley slot 16E is further provided with parallel sides 163. The positioning member is disposed in the limiting slot 161E, and the positioning member 31 is partially exposed to the corner M2 of the connecting slot 4 via the limiting hole 162E. The clips I have 30E having an arc-shaped clamping section 32E, and the clamping section 32E is received in the receiving groove 16E and contacts the outer side of the positioning member 31E and the two ends of the clip (four) and 32E are formed. a chord, the chord length is smaller than the diameter of the accommodating groove 16E. Thus, the nip portion 32E can move the positioning member 31E toward the limiting hole 162E to expose the inner side of the positioning member 31E to the corner 142' of the connecting groove 14 and The inflammatory element 継 is prevented from being detached from the accommodating groove 16E. The two holding portions 32E of the clamping member 30E are respectively formed with a parallel portion 33E with respect to the two straight sides 163E of the receiving groove 16 , and the respective contact of the two parallel segments 33E is flat in the receiving groove 16E. On the straight side 163E, the clamping jaw 30E is prevented from rotating relative to the connecting section 12. The shape of the clamping member 汕e of this embodiment is a structure in which a metal wire has been folded, and the positioning member 31E is a ball-shaped structure. The above description is only a preferred embodiment of the present invention, and when it is not possible to limit the value of the rails, the change in the value of the rail or the equivalent element is replaced by the following or the scope of the patent application of the present invention. Equal variations should remain within the scope of the invention patent. ... [Simple description of the diagram] Figure 1: The three-dimensional appearance of the first-day-head of the head.
